Title: Method of preparation of activated manganese dioxides
IPC: B01J23/16
Filed: 1962-08-28
Abstract: Manganese dioxide is produced by precipitating so-called manganous hydroxide, Mn(OH)2, from a manganous salt solution, oxidizing the precipitate and reacting it with an acid of dissociation constant greater than 10-5 at 25 DEG  C. The manganous salt solution, e.g. manganous sulphate solution, may be prepared from low-grade manganese ores.  Impurities are removed before addition of ammonia or caustic soda solution to precipitate the Mn(OH)2.  The latter is washed and oxidized, e.g. by bubbling air or oxygen through a suspension at pH 8-9, to yield in fact Mn2O3. 2H2O.  Acids specified are: sulphuric, nitric, hydrochloric, acetic, sulphonic and chloroacetic.  Manganous salts are also formed during acidification and can be returned for Mn(OH)2 precipitation. Inorganic salts, e.g. potassium ferrous sulphate, potassium ferric sulphate and the sulphates of Al, Li, and Mg, which may be added with the acid to the extent of 0.1-2.0% by weight of the oxidized Mn(OH)2, influence the structure of the product, of which they may form a part.

Filed: 1920-11-29
Abstract: 175,449. Williamson, C. M., and Laws, F. C. V. Nov. 29, 1920. Aeronautical apparatus.-Relates to automatic film cameras, for use on aircraft, of the kind in which the film-changing and shutter-setting mechanisms are operated by a train of gearing, including a mutilated wheel, driven by an air screw or by a separate power unit. The invention consists in (a) means for actuating the capping flaps and for actuating a pad which presses the film against a glass plate during the exposure, (b) means for driving the receiving spool and a film-measuring drum; (c) arranging in a compartment in the camera a number of instruments and means for taking a series of photographs thereof along the edge of the film, and (d) shutter release mechanism. In the apparatus shown, the mutilated wheel 6, Fig. 1, is geared to a shaft 1 which is driven by an airscrew or otherwise. During part of the revolution of the wheel 6, a stud 33 at the side of the wheel depresses a lever 32 which is connected to a vertical slide 31, Figs. 1 and 3. The slide 31 lowers the pad 28 on to the film by means of the lever 30 and opens the flaps 37 by means of the links 35 connected to cranks 36. After the exposure, the upward movement of the lever 32 under the influence of the weight of the capping flaps rotates the wheel 6 past its gapped portion into mesh with its driving-wheel 5. Before the exposure the wheel 6 is held with the gapped portion registering with the wheel 5 by a detent lever 50 adapted to be disengaged by the shutter roller 48. The wheel 6 is connected by a link 7 to a spur-wheel 8, or segment, which rotates the receiving-spool through differential gear, shown separately in Figs. 6 and 7. The receiving-spool is rotated only when the wheel 15, carrying the planet pinions 12, is locked bv a pawl 26. This pawl 26 is carried by a cranked lever having a stud 22 adapted to engage a notch 23 in the disc on a measuring-drum. The lever is turned by a stud 25 on the wheel 8 to release the measuring-drum and simultaneously to start the rotation of the receiving-spool. A number of recording-instruments are arranged in a compartment within the camera casing and have their faces illuminated by electric lamps 39, Fig. 3. A series of photographs of these instruments is taken along the edge of the film through a series of small lenses 40. The shutter detent 45, Fig. 1, is actuated by a solenoid 43 controlled by a time switch.
